Tontitown,  Arkansas,  April  26,  2005  P.A.M.  Transportation  Services,  Inc.
(NASDAQ:  PTSI)  today  reported  net  income of $2,903,387 or diluted and basic
earnings  per share of $.26 for the quarter ended March 31, 2005 compared to net
income  of  $2,030,817  or  diluted and basic earnings per share of $.18 for the
quarter  ended March 31, 2004. Operating revenues excluding fuel surcharges were

Robert  W.  Weaver,  President of the Company, commented, "Our continued efforts
over  the  last few quarters focusing on rates, cost containment and operational
efficiencies  are  producing  more  positive  results.  The results of our first
quarter  ended  March  31,  2005  show  a  43%  increase in net income and a 44%
increase  in  earnings  per share versus our first quarter ended March 31, 2004.
These  improved  results  are  indicative  that  the changes we have focused our
efforts  towards  over  the last several quarters are beginning to show benefits
and were the right moves for the company."
